Embodiment 1

[0023] figure 1 Schematic diagram of an irradiation reactor for continuous treatment of industrial wastewater by an electron accelerator, including a nozzle 2 and an irradiation container 4 . Said irradiation container 4 is arranged at 300 mm below the scanning window of the electron beam accelerator, a flat nozzle 2 is arranged on the side wall of the irradiation container 4 respectively, and a material outlet 5 is arranged below the irradiation container. Waste water 1 is sprayed from nozzle 2 . The shape of the nozzle 2 is as attached figure 2 As shown, it presents a flat trapezoidal shape, with a wide and thin front end and a narrow and thick rear end. The connection between the irradiation container 4 and the nozzle 2 is a threaded connection, that is, a section of internal threaded straight pipe is welded to the side wall of the irradiation container 4, and the rear end of the nozzle The end is made into a straight pipe with external thread.

Abstract

The invention discloses an irradiation reactor for continuously treating industrial wastewater under cooperation of an electron accelerator, and a method for the irradiation reactor, and belongs to the field of application of nuclear technologies and environmental protection. The irradiation reactor comprises nozzles 2 and an irradiation container 4; and the irradiation container 4 is established 200 to 400mm below a scanning window 6 of the electron accelerator, each of the side walls of the irradiation container 4 is provided with one flat nozzle 2, and wastewater 1 with certain pressure and flow velocity is sprayed by using the nozzles 2 to form a parabolic water film with certain thickness and width. A certain dose of electron beams are irradiated on the wastewater, and then the irradiated wastewater is discharged by a material discharge port 5, and then enters the next process. The irradiation reactor can be matched with electron accelerators with various types and energy for use, and has the advantages of simple structure, low energy consumption, uniform dose, and the like and is easy to control.

Description

technical field [0001] The invention belongs to the field of nuclear technology application and environmental protection, and in particular relates to an irradiation reactor for continuously treating industrial waste water by an electron accelerator. Background technique [0002] The research on using ionizing radiation to treat environmental pollutants can be traced back to the 1950s. At that time, with the development of nuclear reactors and radiation chemistry, the radiolysis properties of water after being exposed to high-energy rays received a lot of attention. Studies have shown that when exposed to radiation, the system will produce physical and chemical effects (such as denaturation of colloids), chemical effects (such as radiolysis or oxidation of pollutants), and biological effects (such as sterilization and disinfection). In the radiation treatment of wastewater, high-energy rays mainly interact with medium water to excite or ionize to produce a series of free ra...
